Looking for wider soundstage

Nice system. You might add some photos of your system under your UserID… lots of time these questions end can be helped by setup.

For instance, my system’s soundstage was enormously improved by adding absorption behind and toe in adjustment of my speakers. You can see photos of my system under my ID.

I will get a pic posted. 

I'm sure you know but toeing in speakers usually gives you a deeper soundstage while firing them straight ahead should yield a wider soundstage but this also depends on other factors. 

It's going to be a setup issue you got the gear. Waiting on pictures.
